Result of CIRCO2 *

I've been taking it for a month hoping it would give me some pep but nada. I have not gotten any benefits. I'll try 2 more weeks and see.

The jury is still out  *
By Hal B. () - 8/4/2025
I’ve been taking CircO2 for two weeks now and I have to report that any benefit is marginal, at best. I’m not sure if I should take it for another month or not. I may but at the cost it could be non-sustainable, in the long run.

By Richard T. (Clearwater, FL) - 8/3/2025
I tried the circo2 for 3 months and it did nothing for me. Never got the energy they advertised. However, they are an honest company. I sent back the empty packages(which they paid for) and I got a quick refund. This product didn't work for me but may work for you. Everyone is different. Had the stuff worked, I would have gotten more. Since this is a company you can trust if there is a problem, I would say try it.
